I've got eggs in an incubator on day 10. I've also got a hen that is acting broody. Can I take the eggs from the incubator and put them under the hen? My concern is that maybe hens have some way of knowing that eggs are supposed to hatch in 21 days and maybe she won't be ready when these hatch after only 11 days. Or maybe she'll treat them like 2 day old eggs when they are in fact 12 day old eggs and it will be bad for the chicks. Also, I've got 13 in the 'bator. I would only put 7 or so under the hen but AFTER the other 6 hatch, I wonder if it would be okay to put ALL the chicks with the hen so they are all together. Would she reject the ones that didn't hatch under her? And if it is okay to put them all together, WHEN should I do it? Your help is much appreciated.
